it would be so helpful if when applying the box of focus meter a constrained to shape square can be made. i need to shoot product in square 'shape' and when i resize the live view focus meter to be my square it's never really a square anymore. just allow for resize, not resahpe, or allow an option to only resize!
Current workaround
there is none - i 'draw' the square every day and it's never the same twice :-(
